Three-plate mould female mould oblique core drawing structure

Abstract

The invention discloses a three-plate mould female mould oblique core drawing structure. A product with an oblique hole is formed. A three-plate mould is provided with an upper fixing plate, a stripper plate, a female mould plate and a male mould plate which are sequentially arranged. A female mould core is arranged inside the female mould plate. A male mould core is arranged inside the male mould plate. The oblique core drawing structure comprises a limit block, a sliding block seat and a sliding block insert core, wherein one end of the limit block is fixed to the upper fixing plate; a limit sliding groove is formed in one side of the limit block; the sliding block seat is arranged on the female mould plate; a limit pin is arranged on the side, close to the limit block, of the sliding block seat; the limit pin is arranged inside the limit sliding groove; an oblique guide groove is formed in the bottom end of the sliding block seat; one end of the sliding block insert core is provided with a guide rail; the guide rail is arranged inside the guide groove of the sliding block seat in a sliding mode; the oblique hole of the product is formed in the end, away from the sliding block seat, of the sliding block insert core. As the sliding block seat of the structure does not occupy large sliding and mounting space like a sliding block in the prior art, the mould structures is more suitable for products with small sizes.

Description

【Technical field】 [0001] The invention relates to an oblique core-pulling structure of a female mold, in particular to an oblique core-pulling structure of a three-plate mold female mold. 【Background technique】 [0002] see figure 1 , figure 1 It is a schematic diagram of the structure of a product. As shown in the figure, the product 100 has an oblique hole 101 on it. [0003] see again figure 2 , figure 2 It is shown as an oblique core-pulling structure of a three-plate mold mother mold in the prior art. for figure 1 The product 100 shown in , because its inclined hole 101 is not consistent with the mold opening direction, so it is a barb in the mold opening direction, so it needs to be withdrawn before the male and female molds are opened. Such as figure 2 The three-plate mold shown includes an upper fixed plate 102, a stripping plate 103, a female template 104, and a male template 105 set up in sequence. The mold opening is carried out for the first time, the...
